Summary
The development of treatments that restore vision assumes that the output neurons of the retina remain intact. Yet, there is now considerable evidence that the neurons that signal from the retina to the brain are altered in those that have degenerative diseases of the retina. Here, we will examine the cause of these cellular changes in an animal model and seek to prevent the loss of output neurons. This information is crucial for the development of treatments that seeks to restore vision.

Summary
Diabetes is the leading cause of blindness in the working population. In some patients with diabetes, blood vessels within the retina proliferate, haemorrhage or cause retinal detachment. The underlying changes within the retina that lead to the proliferation of blood vessels are not well understood. One of the factors that leads to changes in retinal blood vessels is an increase in growth factors from cells within the retina called Muller cells. Muller cells are vital for the normal function of ....Diabetes is the leading cause of blindness in the working population. In some patients with diabetes, blood vessels within the retina proliferate, haemorrhage or cause retinal detachment. The underlying changes within the retina that lead to the proliferation of blood vessels are not well understood. One of the factors that leads to changes in retinal blood vessels is an increase in growth factors from cells within the retina called Muller cells. Muller cells are vital for the normal function of the retina and are known to be abnormal late in diabetes. They may also be dysfunctional early in diabetes and could play a significant role in causing the early changes seen in diabetes. Therefore a good understanding of how Muller cells change and the time at which they change is vitally important to gain a better understanding of the defects that are associated with diabetes. Furthermore, an understanding of the basic underlying cellular changes that occur in dibaetes will aid the development of more specific therapeutic agents in the future.Read moreRead less
